AC TRV EXPANSION VALVE. The thermostatic expansion valve (TRV) is a key component of the automotive air conditioning refrigerant circuit designed to meter and atomize refrigerant before it enters the evaporator. The valve regulates refrigerant flow according to evaporator outlet temperature and pressure, ensuring efficient heat exchange and stable cabin cooling performance. The assembly consists of a calibrated orifice housing, temperature-sensitive diaphragm element, spring mechanism and high/low pressure ports. Its operating principle is based on adjusting the flow area in response to refrigerant temperature, preventing evaporator icing and compressor damage. Failure symptoms include insufficient cooling, evaporator freezing, abnormal pressure readings and irregular compressor cycling. Causes may involve contamination, valve sticking or internal wear. Our catalog includes genuine OEM TRV valves, quality aftermarket replacements and inspected used units free from structural damage. Used parts are checked for mechanical integrity and proper sealing surfaces. Selection is based on VIN number, AC system type, compressor model and refrigerant specification. System flushing and receiver-drier replacement are recommended during installation. Timely replacement ensures efficient cooling and compressor protection.
